for the birds: You don't have to have actual sex to get an STD. There are other ways, other sexual things you can do that don't involve sex, but could still spread disease.
just get a test first...both of you...you never know if you're the one that has it. even if you are both virgins, you should still get checked because your partner could have been born with it, if their mother got pregnant and had AIDS. we learned about this in science the other day. it can be passed on like that.
If you want to wait then wait. Only you know when you're ready to have sex.
If you think you're ready and still afraid of contracting a sexually transmitted disease then have your partner get tested. If they're your bf/gf then I'm sure they won't mind to do that for you. If you're considering casual sex with different partners then I suggest condoms and too choose your partners wisely because you can never be to careful, y'know?
I think in only one country there are women barley allowed to be monks I forgot which one but I remember cause I read and was like "Oh interesting *continues with my business*"
But being a monk makes no more sense than being a nun if you don't believe in a higher spiritual being or cosmic force known as god.
